Abstract: ABSTRACT OF THE DISCLOSURE         A picture data memory system includes a page memory for storing both color gradation and black/white concentration data of a picture to be processed.  A color scanner produces  either  color gradation data or black/white concentration data of a draft picture scanned thereby.  Since the resolution of color picture data can be much lower than the resolution of black and white picture data,  color picture data is scanned at a resolution of 3 lines/mm while a black and white picture is scanned at a resolution of 12 lines/mm.  The number of bits of color gradation data and black and white concentration data written into each address of the page memory are set to be equal to each other, so that 4 picture elements of 4 bits of black and white data are stored in each address of the page memory while 15 bits + 1 redundant bit are stored for each picture element of color data in a particular address of the page memory.

Abstract: Abstract Apparatus for receiving a step-form input signal and providing a limited slew rate output signal in response thereto comprises an amplifier that is operative to provide at its output terminal a current that is variable linearly between a maxi-mum value of one polarity and a maximum value of the opposite polarity when the potential of its input terminal relative to its output terminal varies within a predetermined range.  The magni-tudes of the two maximum values are dependent on the magnitude of a control signal applied to a slope-control terminal of the amplifier.  The ap-paratus also comprises a resistor connected between the output terminal of the amplifier and an output terminal of the apparatus, and a capacitor connected between the output terminal of the apparatus and a reference potential level.

Abstract: Abstract of the Disclosure A synchronous PCM digital transmission system including multilevel multiplexing wherein the higher order multiplexers interleave two or more tributary signals each of which comprises a multiplexed plurality of subtributaries.  Multiplexer framing is achieved by means of an auxiliary frame pattern or byte, FT, which is slidable within the subscriber-defined frames.  Each multiplexer in the system re-frames or slides FT and its associated overhead so that the FT bytes at each multiplexer are synchronized.  The FT bytes can be used to frame or synchronize scrambling and de-scrambling circuitry.  This concept provides multiplexer framing and yields high-speed multiplexed signals which are all exact multiples of the system clock rate, using relatively simple circuitry compared to competitive designs.

Abstract: METHOD AND APPARATUS FOR TEMPERATURE CONTROL              IN THERMAL PRINTERS Abstract of the Invention A thermal printing apparatus for printing on a thermal print medium (10) having a conversion temperature (TC) to which the thermal print medium must be raised to cause printing to occur. The apparatus comprises a thermal print element (40) and exposure means for providing energy to the print element at a first average rate for a time sufficient to raise the temperature of the print element from below the conversion temperature to a temperature above the conversion temperature, and for then providing energy to the print element at a second average rate, the second average rate being less than the first average rate but sufficient to maintain the temperature of the print element above the conversion temperature. The exposure means comprises print enable means (100) for generating an enable signal defining the total length of the energizing interval, modulation means (102) responsive to the enable signal for generating a strobe signal comprising a first pulse (84) followed by a series of second pulses (86), and driver means (50) for energizing the print element in response to the strobe signal pulses. The first pulse has a first pulse length sufficient to raise the temperature of the print element above the conversion temperature. Each second pulse has a second pulse length less than the first pulse length, and the series of second pulses have a duty cycle selected to maintain the temperature of the print element above the conversion temperature.

Abstract: Adaptive Defrost Control for a Refrigerator Abstract An adaptive defrost control for a refrigeration device  alternately operated  in  cooling  and  defrosting cycles includes means for detecting the rate of change of temperature of an evaporator of the refrigeration device during  a defrosting  cycle,  means  for  determining  the length of time the rate of change of evaporator tempera-ture remains at suhstantially zero and means for estab-lishing the duration of a subsequent cooling cycle in dependence upon the determined length of time.  The de-termined length of time is indicative of the magnitude of the frost load that formed on the evaporator and the length of the next cooling cycle is adjusted in accor-dance therewith so that the magnitude of the frost load built up on the evaporator in subsequent cooling cycles is forced toward a value which increases the efficiency of the refrigeration device.

Abstract: REMOTELY OPERATED HATCH COVERS FOR TANK TRUCKS AND THE LIKE ABSTRACT OF THE DISCLOSURE           An air cylinder operates a loose link cam fixed to a rod which pivots the hatch cover which is normally latched closed.  As the cylinder is operated, the first portion of  the movement  unlatches  the  cover  and  the remainder of  the movement swings  the cover up to an over centre position whereupon it falls by gravity to the fully opened position without any further movement of the cylinder.   The loose link cam permits the cover to move through approximately  180°  during the opening motion.          When closing the cover, the same action takes place with the latch moving to the closed position by means of a spring and being displaced by the cover falling to the closed position by gravity once it has been moved by the loose link cam to the over centre position.   The upper surface of the latch hook is curved so that the edge of the cover cross bar strikes the latch and displaces same as the cover closes and which is then returned to the latching position by the spring.
